Incredibly good puzzle! Both the initial exploration of the puzzle and the optimization are both flawless. One of the best puzzles. The intended path being obsoleted doesn't detract from the puzzle for me. Who knew numbers could make an interesting pit level. Great puzzle! It's simply good. Oh, I demoted it to Masters!.. Well, it's not that hard either. Very neat trick! I like the process of elimination you can do in this level. There are three solutions actually.
